Hey, it would be useful if you posted the code you're using to access Inventor (or at least part of it).

I have figured out the exact issue as what happening.

There is no issue while changing Model & User Parameters from an External Application but if any User Parameters type is Text and it has been changed there comes the issue.

I'm using the below Code for changing the Text Parameter.

Create a New Part and add a Text Type User Parameter and name it as "Text_Param" and Just run the below code and try to close the Part Manually Inventor Starts Crashing.

Public InvApp As Inventor.Application
InvApp = System.Runtime.InteropServices.Marshal.GetActiveObject("Inventor.Application")

Dim oParameters As Inventor.Parameters

oParameters = InvApp.ActiveDocument.ComponentDefinition.Parameters

oParameters.Item("Text_Param").Expression = """Text"""

InvApp.ActiveDocument.Update()
